Yeah, and you can even like using Google to pick your next move, when you are playing in your living room. So? Who the hell cares?
But in a tournament you will play by the rules, and the game needs to be designed with these rules in mind and put a system in place to make these rules have meaning and be enforced, rather than being a matter of self-restriction.
You are REALLY trying to be disingenuous about this, uh.
What's next, your good old "appeal to popularity"? Dismissing what forum dwellers and D&D nerds think because "The majority of the casual players will be happy anyway"?
You can use a clock or not. That's self-restriction.
I don't think there are any BG3 tournaments.
But in a tournament, all the players agree to the established rules. You are free to establish rules with other players you might want to multiplayer with.
You are not, however, free to establish rules for other players you aren't playing with.
Nothing I have said is disingenuous. It all makes sense. It's not difficult to parse.
